Who

I stepped out on my lawn tonight
To catch a breath or two
Of cool night air when with a blare
An Owl questioned "Who?".
"Well, it is I", was my reply
"And now, just who are you?"
Then in a short he did report
Again with that same "Who".
"You", I said, "Is who", I said
With some authority
"Now who are thee, up in that tree?"
And "Who" again said he.
"Oh! Now I see, when uttered thee
From high up in that tree
'Who' was thy introduction
And not a question be.
So, Who is you and I am me.
I'm glad we talked this out.
Come again my feathered friend
You're welcome here about."
